Feature description

Lots of galleries over the years (even the default one, atleast for samsung) has had a masonry grid option which instead of every image in a cropped square grid, has the images in the correct ratio and size, placed together. The example i use is not even from a gallery app, however one quick google search will show exactly what i mean if you need to be sure.

Why do you want this feature?

Previewing images looks alot better in masonry form rather than having them cropped and needing to click on them, i know theres an option to not have thumbnails cropped, however it does not look good and is not the same as the masonry grid.
